Circa 300kWp across eleven Sainsbury's stores — Staines, Calcot, Bognor Regis, Northampton, Northwich, Thanet, Heaton Park, Portishead, Ilford, Sunderland and Bedford. A genuinely national rollout delivered with Kingspan, ISG and KIER.

Circa 300kWp across eleven Sainsbury's stores — Staines, Calcot, Bognor Regis, Northampton, Northwich, Thanet, Heaton Park, Portishead, Ilford, Sunderland and Bedford. A genuinely national rollout delivered with Kingspan, ISG and KIER.
A national programme spanning the length of England, delivered to one specification.
Eleven stores spread from Bognor Regis on the south coast to Sunderland in the north east, taking in Staines, Calcot, Northampton, Northwich, Thanet, Heaton Park, Portishead, Ilford and Bedford along the way.
National rollouts are logistics problems as much as electrical ones. Materials, access equipment and teams have to arrive at the right store in the right week, and each site needs its own structural check, its own electrical design and its own network operator notification.
What holds it together is a single specification applied everywhere. The customer walking into the Sunderland store should be getting exactly the same quality of installation above their head as the one in Portishead.
Circa 300kWp delivered across eleven trading supermarkets nationwide.
Photovoltaic arrays installed across eleven Sainsbury's stores from the south coast to the north east.
Programme, materials and teams coordinated across eleven sites in eleven different regions.
Individual structural assessment, electrical design and DNO notification for every store.
Every store remained open and trading for the duration of its installation.

Circa 300kWp added across eleven stores, contributing to Sainsbury's estate-wide carbon reduction.
A single point of responsibility across a national programme rather than eleven local arrangements.
MCS certified and NICEIC approved at every store, with consistent documentation for the whole rollout.
Not one store lost a day's trading to the installation programme.
This programme, the 1.2MWp across six further Sainsbury's stores, ten Tesco stores and approximately forty Aldi stores add up to a retail solar track record few regional contractors can match.
We are based in Queensferry on Deeside, and that is where our surveys, our design work and our core team sit. National reach has never meant losing the local base — it is why a business in Chester or Flintshire gets a contractor with Tier 1 retail experience and a local phone number.
Whatever your building type, we survey it, design for it and certify it. Talk to us about commercial solar panel installation, or browse the full solar portfolio.
